I was cleaning my coffe machine and suddenly this thought hit me.
we drink a lot of coffee.

Many gardeners use coffee, but I heard different opinion on it. Some say it's good, some say it's not.
Do you use it with your daylilies?
How do you use it?
The coffee I have is the rest of the capsules which is obviously drained by water and it's wet.
Any opinion and advice is very welcome, many thanks!

I collect all my coffee grounds and tea bags to bury into the beds. My daylilies seem to be happy with that. Any left over cold coffee I pour onto anything that looks thirsty. The capsules are time consuming to open, I usually collect them in a bucket and save for a "rainy day" to open and empty. If I don't want to make the trip out back to the flower beds, my composter is closer to the house.

Just a note: I drink my coffee and tea with no dairy or sugar : so left over coffee is good to use. Wouldn't think that the sugar or dairy would be good for the garden it actually might attract the unwanted.

I know it will attract slugs! I have used it in my slug traps and it works. One time when my garden was featured on a garden tour, a visitor to my garden left a half finished iced coffee in the garden. It was one of those plastic cups with a lid with a hole in it for a straw. The next morning when I found it, it was full of dead and dying slugs.

Valerie, good to know! I drink the sugary kind, so I'll be certain to make a bit extra if I see slugs. I don't think I have ever seen a snail in the garden, but I do find slugs occasionally.

I've heard beer is an effective trap, too...

Learning about sweet coffee luring slugs is the silver lining for the guest leaving the cup in your garden. I'm sure there are those out there who might think beer is entirely too good to use as slug bait, but hey, coffee can be sacrificed...

Jerry Baker, who used to write a lot of books on organic gardening, etc. used to advocate coffee grounds around Japanese maples in the spring to enhance their red color. I think the trace element was potassium, as he also mentioned banana peels and crushed egg shells. Crushed egg shells were also recommended around hosta to help control slugs. HE had all sorts of concoctions, including a modified version of the "Hooker Formula" first us d on roses, but also used by numerous daylily growers. I used it for a while and it uses a lot of good elements like Epsom salts, but I found that the fish emulsion was NASTY smelling and attracted skunks, who would dig up entire plants to look for fish!

There's more nitrogen in coffee grounds than potassium although it does have some potassium (potassium is a major nutrient rather than a trace element because it is needed in much larger amounts). Concoctions was a good word, his mixtures of household cleaning products etc. were not "organic".

For what it's worth 4th, I have four daylilies in my 🍓 strawberry bed and I put a bunch of coffee grounds in there last year and they did well. Strawberries (and other fruit plants) love coffee grounds! I think the daylilies are good with or without, they probably don't care either way. It's possible the slightly higher acidity might affect bloom color, I suppose, but if it does, it is likely to be very minor. (I put coffee grounds around my hydrangea to try to keep it blue... I don't like it so much when it is pink-flowered)

Depending on the coffee grounds they aren't necessarily acidic or significantly so. I tested mine and they were about pH 6.8. That's about the same as the soil pH here so wouldn't do anything to lower it. This article by Dr. Linda Chalker-Scott suggests they can even be alkaline in some cases:

The only time I ever tried coffee grounds around a daylily it died! I think it was probably coincidence though and it was really winter that did it in. They can negatively affect some plants though (also discussed in the above article).

Ohh yea I take for granted the area I have sometimes and forgot you have a small area you are dealing with. What about making a bucket composter. If you can get access to a 18L bucket, or something smaller. Drill some 1/4 inch size holes in the lid and sides near the opening. Then add your grounds and kitchen scrapes etc... and put the lid on it. When it needs to be rotated or aerated, you can just roll it around in the lawn. Do you have someplace to keep it? There are some counter top composters too, but I couldn't recommend or begin to say how they work.
